CLAMP.

SPECIFICATION forming part of Letters Patent No. 577,669, dated February23, 1897.

Application filed June 3, 1896. Serial N0- 594=,081. (N0 model.)

To all whom it may concern.-

Be it known that I, JOHN STRANG, a subject of the Queen of GreatBritain, residing at Quebee, Canada, have invented certain new anduseful Improvements in Clamps; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to woodworkers clamps, and more particularly to aclamp for holding a block of wood being operated on to construct thehull of a toy boat.

My object is to provide an improved, simple, and cheap clamp adapted tohold a block of wood While being shaped into a toy boathull, so that thehands of the operator will be free for use.

The invention consists of certain novel features and combinationsappearing more fully hereinafter.

In the accompanying drawings, Figure 1 is a side elevation; Fig. 2, asectional side elevation. Fig. 3 is a plan View, and Fig. 4 aperspective view showing the shield removed and used as a cover.

A designates a base preferably of rectangular form. A holder B issecured to this base by screws. (Not shown.) This holder or box is arectangular structure having three sides securely fastened together andto the base, but one of its ends 1 is removable, being connected to thesides of the holder by angle-irons 2 and 3.

One of the sides of the holder is provided with sets of upper and lowerscrew-threaded openings 4: and 5, located near the ends of the box.Adjustable thumb-screws 6 and 7 operate in these openings. A thumb-screw8 passes through the removable end 1.. A triangular brace 9 has itssmaller base connected to the front end of the box and extends theentire width thereof.

The base A is provided with a triangular notch 10,which extends thewidth of the holder and is immediately beneath the brace J.

The numeral 11 designates an inclined shield. which is of approximatelythe same width as the holder and has its lower beveled end snuglyreceived in the notch in the base. The base is also provided with anotch 12, which receives the lower end of a handle 13,

whose upper end is adjustably connected to the shield by a screw 14:,which fits looselyin the handle,butis threaded through the shield. Byadjusting the screw the shield may be held snug against theupwardly-inclined face of the triangular brace 9.

The shield is slightly narrower than the holder, so that when it isremoved itmay he slid in grooves 14: in the holder and, in connectionwith a slide 11, be used as a cover therefor, so that the whole devicecan be made into compact form.

The invention is used in the following manner: The block of wood isplaced in the holder and the thumb-screws adjusted to clamp it inposition. The lines of the hull having been marked on the block, theworkman grasps the handle 13 with his left hand and manipulates thegouge or chisel with his right hand. If it is desirable that both handsbe free, the end of the base may be pressed against some fixed object.After the upper portion of the hull has been finished the thumb-screwsmay be taken out and placed in the lower openin gs and the blockremoved, turned over, and replaced, so that the bottom of the hull andthe keel can be formed. If the block is longer than the holder, theremovable end can be taken off and only the side thumb-screws employed.In any event it will be observed that the shield protects the hand frominjury occasioned by slipping of the tool when the handle is used. 1

Having thus described the invention, what is claimed as new is 1. In awoodworkers clamp, the combination with a holder and clamping devicesfor securing the work in the holder, of a handle, and a shield therefor,substantially as described.

2. In a woodworkers clamp, the combination with a holder and clampingdevices for securing the work in the holder, of a handle, and anupwardly-inclined shield therefor, substantially as described.

3. In a woodworkers clamp, the combination with a base, of a holder andmeans for clamping the work therein, an upwardly-inclined shieldconnected to the base, and a handle protected by said shield,substantially as described.

4. In a woodworkers clamp, the combination with a base, of a holder andmeans for specification in the presence of two subscribclamping the Worktherein, an npwardly-ining Witnesses.

clined shield, a brace interposed between the shield and the holder, anda handle interposed JOHN STRANG' 5 between the base and the shield,substan- WVitnesses:

tially as described. A. G. OUELLET,

In testimony whereof I have signed this J. F. DAGNEAU.
